An Israeli company Argo Medical Technologies has developed a human exoskeleton that can help people with lower limb paralysis to walk. The technology is called ReWalk and “enables wheelchair users with lower-limb disabilities to stand, walk, and even climb stairs.” It is a robotic suit that can be partially concealed by clothing. The users walk with crutches, and the suit senses changes in the center of mass and the limb position to detect and respond to user intentions.
